By some reason images addresses above changed from usual http:audiocircle to http: //106.186.16.116

It doesn't matter whether the link uses audiocircle.com or 106.186.16.116, it's the same address only the latter doesn't require a DNS lookup.

As far as your images, not sure what's going on there. Whether your trying to first add it to your gallery then copying the link into the post, or directly uploading an inserting an image into the post - either way there's no new images in your gallery.
